I have a 100 year old home in Sacramento. We have a pretty good sized lot, for being in the city.
I fenced off a side yard for my 2 chickens & they have this 4x8 coop I lock them in at night.
I have a small yard but did fit this coop against the back fence.
We can see it from our kitchen/living room, so can be entertained by the chicks.
it is 4' by 4' and we have 4 hens.
As you can see, my son likes to play in it as well.
The run next to it is 4 feet by 8 feet
there are a few additions since this but here is my first coop in pittsburgh with 3 chicks. its pretty simple but seems to be working
